Description

Technical Field

[0001] The present invention relates to the technical field of vegetation restoration regulation, and specifically to an efficient water-saving method for desert vegetation restoration regulation. Background Art

[0002] Desert expansion and secondary salinization are the greatest threats to the ecological security of oases in the arid areas of the northwest inland. To some extent, the two are closely related. Conducting joint regulation research on the two from the hydrological mechanism is of great significance for promoting local ecological protection and is also a technical difficulty that needs to be urgently broken through in subsequent ecological restoration in arid areas. The main reason for desertification in the transition zone outside the oasis in the arid area is the large amount of water resources used in the irrigation area, which leads to the retreat of the groundwater phreatic flow field, the decline of the groundwater level in the transition zone, and the inability of vegetation to obtain groundwater recharge, resulting in the desert moving towards the oasis. The main reason for secondary salinization in the oasis is the concentrated use of water resources in the irrigation area and the improper discharge of irrigation return water, which leads to the rise of the underground water level in local areas within the oasis, and the evaporation of soil water brings salts to the surface for crystallization.

[0003] In the existing technology, the water resource supplement for desert vegetation during growth is uneven, which will cause some vegetation in the desert to grow well while some are relatively dry. The main reason is that the water resources during the watering process are not effectively regulated, resulting in uneven watering humidity, and some positions are relatively dry, requiring more water. According to the traditional water replenishment amount, the growth needs of vegetation cannot be effectively met.

[0004] When applying for the present invention, the applicant found through retrieval that the Chinese patent disclosed "A groundwater level regulation method for synergistically alleviating desertification and secondary salinization in arid areas", with the application number "202010986127.0". This patent mainly focuses on the critical burial depth of soil desertification, and at the same time conducts joint research on the two problems, analyzes that the key to the above two problems is to control the groundwater level, and proposes a groundwater level regulation scheme for synergistically alleviating desertification and secondary salinization. The physical process and action mechanism of this method are clear, and it is universal for solving desertification and soil secondary salinization caused by unreasonable groundwater level control. However, a large amount of manpower and material resources are required for the critical deep burial of water resources, and the same is true for the work with a large amount of manpower in the desert, which also increases the labor cost. Therefore, according to the applicant's invention, a method is invented that can control the insertion depth of the branch pipe in the desert for water conservation, reduce the regulation cost, and achieve the vegetation restoration effect at the same time. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the existing technology, the present invention provides an efficient water-saving method for desert vegetation restoration regulation, which solves the problem of water-saving control of the insertion depth of the branch pipe in the desert to reduce the regulation cost and achieve the vegetation restoration effect at the same time.

[0010] The regulation method includes the following steps:

[0011] Step 1: Collect humidity data in the desert area. After collection, perform regulated irrigation on the deserts in different areas;

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment:

[0034] As Figures 1-4 shown, the embodiment of the present invention provides an efficient water-saving method for regulating the restoration of desert vegetation, including: an irrigation system and a regulation method;

[0035] The irrigation system includes a water storage tank 1, a collection water tank 4, a main flow pipe 7 and a branch pipe 8. One side bottom end of the water storage tank 1 is fixedly connected with a high-pressure water pump 3. Through the power provided by the high-pressure water pump 3, the water source is circulated through the main flow pipe 7 through the oasis 5 to the desert 6. The output end of the high-pressure water pump 3 is fixedly connected with the main flow pipe 7. The bottom end and both sides of the main flow pipe 7 are respectively fixedly connected with a number of branch pipes 8. The bottom end of the branch pipe 8 is fixedly connected with a ground-inserting pipe 9. According to the pre-buried branch pipes 8 in the desert 6, they are inserted into the plant roots. The ground-inserting pipe 9 is first inserted to a depth of 10 cm at the plant roots, and the pointed cone inserting pipe 10 will be inserted 50 - 70 cm underground. Through the action of the pointed cone inserting pipe 10 after the water source is circulated through the branch pipe 8, the water source can be dispersed to both sides. The middle part of the inner wall of the ground-inserting pipe 9 is fixedly connected with a fixing frame 13. The bottom end of the fixing frame 13 is fixedly connected with the pointed cone inserting pipe 10. The top end of the fixing frame 13 is fixedly connected with an electric telescopic rod 12. When the electric telescopic rod 12 extends, the sealing ring 14 is inserted into the inner wall of the branch pipe 8 to block it, completing the water-stopping function. The top end of the electric telescopic rod 12 is fixedly connected with a support plate 15. The top end of the support plate 15 is fixedly connected with a sealing ring 14. The sealing ring 14 is hermetically inserted with the branch pipe 8.

[0036] Both the upper and lower ends of the tapered intubation tube 10 are fixedly connected with humidity sensors 11. The humidity sensor 11 at the bottom end can sense the humidity at a depth of 70 cm underground, and can sense the control of the water replenishment amount. It extends downward through the action of the tapered intubation tube 10 to the root position. When the water source at the root position circulates and overflows upward, the humidity sensor 11 at the top end senses the humidity, and sends a signal to the controller after sensing to stop the water supply. The irrigation system includes an inland river 2, an oasis 5, and a desert 6. In the middle of the main circulation pipe 7 above the oasis 5, a water storage tank is fixedly connected. In the middle of the top end of the water storage tank, a number of collection pipes 17 are fixedly connected. In the middle of the inner wall of the collection pipe 17, a fixing ring 18 is fixedly connected. There is a fixing ring 18 inside the collection pipe 17. When the water flows downward, the lower pressing plate 19 will be pressed downward by the gravity, and at this time the spring is elastically stretched, and the water source will effectively flow into the water storage tank. After there is no water flow pressing down, the spring closes through elasticity, which can prevent the evaporation phenomenon of the water source inside the water storage tank. On the four sides of the bottom end of the fixing ring 18, bellows 16 are fixedly connected. A support spring is sleeved inside the bellows 16. The support spring and the bottom end of the bellows 16 are both fixedly connected with a lower pressing plate 19. The lower pressing plate 19 is conical. The top end of the collection pipe 17 is fixedly connected with a collection water tank 4. Above the main circulation pipe 7 at the oasis 5 position, the water source can be collected into the water storage tank through the collection water tank 4 to achieve the collection and utilization of resources. The water source inside the water storage tank can be pressurized and circulated into the main circulation pipe 7 again through the second water pump for use. The collection water tank 4 is semi-circular, and a fixing net is fixedly connected to the top end of the collection water tank 4.

[0037] The regulation method includes the following steps:

[0038] Step 1: Collect humidity data in the desert area. After collection, carry out regulated irrigation on the deserts in different areas. The depth of collecting humidity data in the desert area is 60 - 80 cm. When the humidity is relatively wet at a depth of 60 - 80 cm, it indicates that the water content is good, and a small amount of water can be appropriately supplemented to reduce the waste of water resources and maintain the water required for the growth of vegetation.

[0039] Step 2: The branch pipe 8 is inserted into the positions in the desert that need to be irrigated, and the tapered intubation tube 10 is inserted into the desert underground, and the ground insertion pipe 9 is inserted and matched with the ground, which is convenient for the subsequent accurate circulation of the water source underground and is not likely to appear scattered circulation. Through the action of the tapered tube 10, the water source can be dispersed outward to fully supplement and absorb the water for the roots. The depth of the tapered intubation tube 10 is 50 - 70 cm, and the depth of the ground insertion pipe 9 is 10 cm. Through the setting of 10 cm, the seepage of water can be prevented, and at the same time, the water source can be evenly provided for the roots from top to bottom.

[0040] Step 3: Humidity sensors 11 are used at the bottom ends of the tapered cannulas 10 to sense humidity. When the humidity in the desert is humid, the irrigation volume can be controlled. When the humidity in the desert is dry, the irrigation with more water can be carried out to improve the vegetation restoration effect.

[0041] Step 4: Rainwater is collected above the oasis 5 through the collection tank 4 to provide for the reuse of resources. And the water resources can flow through the collection pipe 17 into the interior of the water storage tank and then flow into the interior of the main circulation pipe 7 again through pressurization.

[0042] Step 5: The sealing ring 14 at the top end of the electric telescopic rod 12 is inserted into the branch pipe 8 to increase the sealing performance and prevent the dripping of water sources, resulting in the infiltration and waste of water resources.

[0043] Working principle of the irrigation system: During use, the water storage tank 1 stores the water source in the inland river 2. Subsequently, the high-pressure water pump 3 provides power to make the water source flow through the main circulation pipe 7 through the oasis 5 into the desert 6. Then, according to the pre-buried branch pipes 8 in the desert 6, they are inserted into the roots of the plants. The ground-inserted pipes 9 are first inserted 10 cm deep into the plant roots, and the tapered cannulas 10 are inserted 50 - 70 cm underground. Through the action of the branch pipes 8 to circulate the water source, the tapered cannulas 10 can disperse the water source to both sides. The humidity sensors 11 at the bottom ends can sense the humidity at 70 cm underground, and can sense and control the amount of water replenishment. Through the action of the tapered cannulas 10, it extends downward and circulates to the root position. When the water source at the root position circulates and overflows upward, the humidity sensors 11 at the top end sense the humidity, send a signal to the controller after sensing, and after the controller receives the signal, it sends a signal to the electric telescopic rod 12. Then the electric telescopic rod 12 extends, and the sealing ring 14 is inserted into the inner wall of the branch pipe 8 to block and complete the water stopping function. And above the main circulation pipe 7 at the oasis 5 position, the water source can be collected into the water storage tank through the collection tank 4 to achieve the collection and utilization of resources. The water source in the water storage tank can be pressurized again through the second water pump and flow into the interior of the main circulation pipe 7 for use. A fixing ring 18 is arranged inside the collection pipe 17. When the water flows downward, the lower pressing plate 19 is pressed downward by the gravity, and at this time the spring is elastically stretched, and the water source can effectively flow into the interior of the water storage tank. After there is no water flow pressing down, the spring closes through elasticity, which can prevent the evaporation phenomenon of the water source inside the water storage tank.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
